Problem 5
Transcribed Image Text:(5) Let
f (11, 12) = (2 +4 (r1)² , 3x2 , 1123)
(a) What are the component functions of f?
(b) Let a = (0, 1) . What is b = f (a)?
(c) Use Calc3 to give the Jacobian matrix of f at a.
(d) Prove using the (limit!!) definition of the (total) derivative that Dfa is equal to your
answer in part (c)
(6) Continuing, we let
g (y1, Y2; Y3) = 6y1 – 5y2 + 3y3
(a) Use the fact that g is linear to give the total derivative of g at b in matrix form.
(b) Use the chain rule to compute the (total) derivative of (gof) at a using ONLY parts
(1d.) and (2a.).
